Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80678, here are decompositions:

  • 7 + 80671 = 80678
  • 67 + 80611 = 80678
  • 79 + 80599 = 80678
  • 151 + 80527 = 80678
  • 229 + 80449 = 80678
  • 271 + 80407 = 80678
  • 331 + 80347 = 80678
  • 337 + 80341 = 80678

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80678 first appears in π at position 53,959 of the decimal expansion (the 53,959ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
